Cuart 5. Lot 869. This illustrates the value of the mixture of maize and oat proteins when fed at the plane of f intake of 7 
per cent of the food mixture. The deficiencies of the grains with respect to inorganic elements and fat-soluble A were made good 
by suitable additions. The results indicate that this protein mixture is inferior to that derived from the wheat and oat kernels 
(Chart 4, Lot 870), for growth was not so rapid, and the animals were somewhat more stunted than with the latter ration. 
The reproduction records on this ration are distinctly below those of Lot 870, on the wheat and oat mixture. Mixtures of maize 
and oat proteins in equal proportions do not appear to be greatly superior to the proteins of either seed fed singly at the same 
plane of intake, but some superiority is evident, since no reproduction has been secured on 9 per cent of either maize or oat 
proteins alone. 
Lot 868 shows that wheat and maize proteins when fed together in equal proportions are ee of so good a quality as are 
those of wheat and oats fed together in a similar manner (Chart 4, Lot 870). The fact that the one female produced three 
litters of young shows clearly that the mixed proteins are better than those of each of the seeds fed singly. These records 
together with those in Charts 4 and 5 show for mixtures of two cereal grains what we have previously demonstrated for 
mixtures of maize and navy beans, viz., that the biological values of mixtures of proteins from seeds are distinctly lower than 
that of the proteins of milk, and emphasize the fact that poor quality of the protein content of the diet is in all probability 
one of the factors in lowering the vitality of those peoples who live during the winter season on a diet restricted to a few arti- 
cles, the chief one being corn bread or wheat bread. Corn bread, salt pork, and molasses constitute in winter almost the en- 
tire source of nutriment of many people in the South today.
